15. even in installations with heating using fan coils or low temperature radiators Moreover ecoGEO heat pumps can provide two different outlet temperatures by simply adding external 3 way modulating valve and a circulating pump without using additional control systems This can simplify installation and reduce cost significantly General Installation Recommendations Geothermal heat pumps in general and ecoGEO heat pumps in particular provide maximum performance when used energy in heating installations fitted with low temperature heat emitters This means the ideal application is underfloor heating using a radiant floor surface as these require low outlet temperatures around 35 C However ecoGEO heat pumps allow outlet temperatures of up to 55 so they can be used in heating with medium temperature emitters such as fancoils convector heaters or low temperature radiators In this type of installations ecoGEO heat pump also ensure maximum efficiency However it should be noted that the increased outlet temperature of the heating system increases the energy consumption necessary for heating the water and thus reduces the energy efficiency that can be obtained with the heat pump Thus an increase in the outlet temperature from 359C to 509C means a reduction in energy efficiency of approximately 2596 To mitigate this effect we recommend over dimensioning the thermal emitters in the heating system to minimize the required outlet temperature
